Description
KW height-adjustable springs for BMW M3 F80. These height-adjustable springs let you set the ride height while retaining the original shock absorbers. Threaded adjustment provides a personalised drop without replacing the entire damping system.
The stated technical adjustment range is 5–25 mm at the front and 5–25 mm at the rear. Choose the product reference that matches the vehicle version and suspension configuration. The Swiss approval document specific to the kit is included.
To comply with the Swiss approval document, lowering is limited to a maximum of −40 mm relative to the original ride height, subject to the conditions in the supplied document. The kit’s technical adjustment range may extend beyond this limit.
